    Chikin Ha, just a short hop from Playa del Carmen, often gets overlooked for its flashier neighbours, but we think that’s a mistake. This cenote system offers a really satisfying cavern dive, especially for those new to overhead environments. We love the feeling of slipping into the cool, fresh water, the light filtering down through the jungle canopy above. Once you’re in, the visibility is usually phenomenal, 30 metres isn’t uncommon, and the formations are genuinely impressive. You’ll follow a well-marked line through various chambers, feeling the subtle halocline where the fresh and salt water meet, a shimmering curtain that plays tricks with the light. Look for the little hogfish and doctorfish darting around, quite at home in this ethereal setting. Our favourite part is probably the "dry" chamber you can surface in, where the tree roots dangle down, reaching for the water below. It’s a great spot for a quick chat and a real moment of perspective. Chikin Ha is perfect for certified cavern divers, or even experienced open-water divers looking to dip a toe into the overhead world with a good guide. It’s a gentle, beautiful introduction to cenote diving, and the entry fee is kind on the wallet too.
